CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent Application Ser. No. 62/351,441 filed Jun. 17, 2016, which is incorporated herein by reference in its entirety.

FIELD OF THE TECHNOLOGY

The disclosed embodiments generally relates to detecting and providing notification of water leaks inside of homes and businesses.

BACKGROUND

Water leaks in homes and businesses cause a tremendous amount of damage to structures and contents. Leaks generally occur from a burst water pipe or leaking faucets or water using appliances. If an occupant is present and the leak is easily visible, water damage can often be prevented. However many leaks occur behind cabinets and in the walls so that even if an occupant is present, the leaks may not be discovered until a very substantial amount of damage has been caused. It is not uncommon for an undetected leak to literally create havoc and require major reconstruction to return the building to a usable state. Moreover, leaks induce the growth of hazardous mold.

Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIG. 1 depicts an exemplary communications network 100 in which certain below illustrated embodiments may be implemented in conjunction therewith.

It is to be understood a communication network 100 is a geographically distributed collection of nodes interconnected by communication links and segments for transporting data between end nodes, such as personal computers, work stations, smart phone devices, tablets, televisions, gaming/media consoles, smart watches, smart wristbands, sensors and or other devices such as automobiles, etc. Many types of networks are available, with the types ranging from local area networks (LANs) to wide area networks (WANs). LANs typically connect the nodes over dedicated private communications links located in the same general physical location, such as a building or campus. WANs, on the other hand, typically connect geographically dispersed nodes over long-distance communications links, such as common carrier telephone lines, optical lightpaths, synchronous optical networks (SONET), synchronous digital hierarchy (SDH) links, or Powerline Communications (PLC), and others.

FIG. 1 is a schematic block diagram of an example communication network 100 illustratively comprising nodes/devices 101-108 (e.g., sensors 102, client computing devices 103, smart phone devices 105, web servers 106, routers 107, switches 108, and the like) interconnected by various methods of communication. For instance, the links 109 may be wired links or may comprise a wireless communication medium, where certain nodes are in communication with other nodes, e.g., based on distance, signal strength, current operational status, location, etc. Moreover, each of the devices can communicate data packets (or frames) 142 with other devices using predefined network communication protocols as will be appreciated by those skilled in the art, such as various wired protocols and wireless protocols etc., where appropriate. In this context, a protocol consists of a set of rules defining how the nodes interact with each other. Those skilled in the art will understand that any number of nodes, devices, links, etc. may be used in the computer network, and that the view shown herein is for simplicity. Also, while the embodiments are shown herein with reference to a general network cloud, the description herein is not so limited, and may be applied to networks that are hardwired.

With the exemplary communication network 100 (FIG. 1) and monitor module 200 (FIG. 2) being generally shown and discussed above, description of certain illustrated embodiments of the present disclosure will now be provided. With reference now to FIG. 3, it is to be understood and appreciated significant development and use of “smart home” related technologies have been made and the smart home sector is advancing rapidly. The illustrated embodiments provide devices, systems and methods for detecting water flow through a conduit for enabling leak flow detection and/or monitoring of water flow to appliances in a property. It is to be understood, water flow appliance devices as referred to herein consists of devices that consume and/or dispense water, such as (but not limited to a: faucet; shower; bath tubs; toilet; clothes washer machine; dishwasher; refrigerator; freezer; HVAC unit; and humidifier). It is to be appreciated that while the illustrated embodiments are for detecting water flow through a conduit, it is to be understood they may be configured to detect other flow types through a conduit (e.g., gas, compressed air, petroleum based fluids (heating oil) and other fluids). For instance, they may be configured to detect natural gas flow or heating oil flow through a conduit leading to a furnace appliance device. However, for ease of illustration and description purposes only, the embodiments illustrated herein are described herein in reference to water flow detection.

The water flow system/device/apparatus illustrated in FIGS. 3A and 3B is configured to detect and provide notification of a water flow leak in a conduit 310 supplying water flow 312 preferably to a destination device 350. The system, designated generally by reference numeral 300, preferably includes a first conduit 310 having a first diameter 314 supplying water flow 312 to preferably a destination device 350 for consuming and/or dispensing the water flow 312. Examples of the destination device 350 include (and are not to be understood to be limited to) a: faucet; shower; toilet; bathtub; clothes washer machine; and dishwasher.

A second conduit 320 preferably concentric with the first conduit 312 is provided for at least a portion of the length of the first conduit 312 wherein the second conduit 320 has a diameter 324 greater than the first diameter 314 forming a space 322 (leak space) between the first and second diameters 314, 324). Further provided is indicator material 326 provided in the leak space 322 such that when breakage is caused in the first conduit 310 effecting a water leak regarding the water flow 312 in the first conduit 310, the water flow 312 in the first conduit 310 is caused to interact with the leak indicator material 326 providing visual indication of the leak in the water flow 312 to the destination device 350.

It is to be appreciated the aforesaid visual indication caused by interaction of the water flow 312 with the leak indicator material 326 may consist of the water flow being a particular color. For instance, when a leak is caused in a conduit 310 providing water flow 312 to a faucet destination device 350, the water flow dispensed from the faucet 350 may have red color qualities to provide user notification of a leak/rupture in the conduit 310 causing the user to rectify the leak so as to mitigate any additional damages caused by the water leak in the conduit 310. In accordance with the illustrated embodiment, the leak indicator material 326 may consist of a color dye material. It is to be further appreciated the leak indicator material 326 may be consist of a liquid, solid or powder like material.

It is to be further appreciated the first conduit 310 is formed of a first material (e.g., copper, plastic, PVC and any other suitable material) and the second conduit 320 is formed of a second material (e.g., copper, plastic, PVC and any other suitable material) which may be either the same or different from the first material. Additionally, the second conduit 320 may retrofitted to be concentric with the first conduit 310 or may be formed in conjunction with the first conduit 310. For instance, in a scenario where the first conduit 310 for supplying a water flow 312 is preexisting in a residence, a home owner may retrofit the second conduit 320 with the first conduit 310 as illustrated and described herein. In continuing with this scenario, the second conduit 320 may consist of multiple sections that attach to one another, via affixing means (adhesive, snap fit pieces, etc.) or detachably assembly means (clamp assembly, threaded assembly, etc.). It is to be further appreciated the second conduit 320 may include a port for introducing, and removing, the indicator material 326 into, and out of, the leak space 322 for a desired purpose.

With reference now to FIG. 3C, yet another illustrated embodiment of the system 300 will be described. As shown in FIG. 3C, a plurality of second conduit sections (320 a-e) are provided relative to conduits 310 a and 310 b, whereby each the leak space (322 a-e) of each second conduit section (320 a-e) is provided with indicator material (326 a-e) providing visual indication of a water leak different than that of another second conduit section. For instance, if a leak occurs in second conduit section 320 a (located in a first floor of a residence), its indicator material 326 a may cause water to be dispensed from a faucet appliance 350 to have a red color (as opposed to if a leak occurs in second conduit section 320 b (located in a second floor of a residence), its indicator material 326 b may cause water to be dispensed from a faucet appliance 350 to have a blue color) providing notification to the home owner of a leak in a section of conduit 310 positioned in the first floor, thus mitigating the often intrusive process to locate such leaks.

With reference now to FIG. 4, another illustrated embodiment of the system 300 is depicted in which the first conduit 410 providing a water supply 412 to a destination device 450 includes a coating of leak indicator material 426 provided on at least a portion of the outer diameter surface of the conduit 410 such that when breakage is caused in the conduit 410 effecting a water leak in proximity to the leak indicator material 426, the portion of the water leak which contacts the leak indicator material 426 is caused to create a reaction providing notification of the water leak. For instance, the leak indicator material 426 may consist of a glycol based material, which when it comes into contact with water, generates a reaction causing smoke 430. Thus, when a leak in conduit 410 occurs in proximity to the provision of the leak indicator material 426, smoke is caused to emit therefrom providing visual notification to a home owner of the leak. It is to be appreciated, the leak indicator material 426 may be selected to generate smoke of a certain color, or the leak indicator material 426 may be selected (e.g., sulfur based product) to provide a certain scent as opposed to smoke when water comes into contact therewith for providing leak notification.

It is to be appreciated the coating of leak indicator material 426 may be retrofitted to the outer diameter surface of the conduit 410 or it may be formed/distributed therewith. Additionally, as also described above with regards to the plurality of second conduit sections 320 a-e (FIG. 3C), a plurality of portions of the outer diameter surface of the conduit 410 is each provided with indicator material 426 providing visual/scent indication of a water leak different than that of another section of the conduit 410 having a separate coating of leak indicator material 426 so as to aid a user in identifying the leak location, as mentioned above.

With reference now to FIG. 5, another illustrated embodiment is shown and described for detecting water leaks in a conduit 510 supplying water flow 512 to preferably an appliance device 550. A first water flow sensor device 520 is associated with a first section 522 of the conduit 510 configured to determine the water flow 512 through the first section 522 and a second water flow sensor device 530 is associated with a second section 532 of the conduit 510 (wherein the second section 532 is preferably located downstream of the first section 522) configured to determine the water flow 512 through the second section 532. Each of the first and second water flow sensor 520 and 530 preferably include a transmitter device for transmitting a respective signal indicative of the determined water flow it is detecting.

A remote computing device 550 is communicatively coupled to the respective transmitters of the first and second water flow sensors (520, 530), whereby the remote computing device 550 is preferably operative and configured to receive the respective signals indicative of the determined water flow from each of the first and second water flow sensors (520, 530). The remote computing device is further preferably configured and operative to determine when the water flow of the second sensor 530 is less than the water flow of the first sensor 520 by a threshold amount so as to provide user notification of a leak occurring in the conduit 510 at a location between the first and second sensors (520, 530).

It is to be appreciated each of the aforesaid first and second sensors (520, 530) may be configured to be wired, or wirelessly coupled to, the remote computing device 550 via any known and suitable transmission means including (but not limited to) Bluetooth, Wi-Fi, RF, wherein each first and second sensor (520, 530) may include a WLAN IP address. It is to be further appreciated the remote computing device 550 may be chosen from the group consisting of: a computer server; a laptop device; a portable computing device; a smart phone device; and tablet device and the like. Additionally, the remote computing device 550 may be configured and operative to communicate with a user computing device (e.g., a portable computing device; a smart phone device; and tablet device and the like) for providing user notification thereon.

It is still further to be appreciated each of the first and second sensors (520, 530) is configured to either invasively, or non-invasively, couple to a section (e.g., 522) of the conduit 510. For instance, when invasive coupling is used, the sensor device may include an impeller device positioned in the conduit 510 for measuring water flow there though, and when non-invasive coupling is used, the sensor device may include a sonar device configured for sonic interaction with the water flow in the conduit 510 for flow measurement. Additionally, the remote computing device 550 may be further configured and operative to meter an amount of water consumed via the conduit 510 contingent upon the flow measurements from one, or both of, the first and second sensors (520, 530) thus providing metering information to a user regarding water consumption.

It is to be further appreciated the system illustrated in FIG. 5 may further include at least one or more secondary water flow sensors (535, 540) associated with a section of the conduit (537, 542) preferably intermediate the first and second sensors (520, 530). As described above with respect the first and second sensors (520, 530), each secondary sensor (535, 540) preferably includes a transmitter device for transmitting a signal to the remote computing device 550 indicative of the determined water flow through the conduit section (537, 542) of the respective secondary sensor (353, 540) it is associated with. The remote computing device 550 is further preferably configured and operative to remotely actuate at least one secondary sensor (535, 540) when it is determined there is a leak in conduit 510 so as to measure the water flow between any combination of the first (520), second (530) and secondary sensors (535, 540) to determine if the leak is between that combination of sensors (e.g., sensors 520 and 540, or between sensors 540 and 530) so as to more precisely locate the leak location along the conduit 510.
